Sky: tell truth on doping or you're out

British cycling team Sky revealed Wednesday that all their riders and management will be forced to sign a pledge, swearing that they have never doped or they will be booted out of the squad. Sky, for whom Bradley Wiggins triumphed in the Tour de France this year, said that all staff must be clean as the sport continues to reel from the Lance Armstrong doping scandal. "Over the coming weeks, we will talk individually with each team member and ask everyone, at every level of the team, to sign up to a clear written policy, confirming that they have no past or present involvement in doping," said a Sky statement. "Should anyone choose not to sign up to our clear policy they will have to leave the team, as will anyone who does sign but is subsequently found to be in breach. "We are making this statement because we believe it is important to be open about the steps we are taking." Sky, who also boast the talents of Tour de France runner-up Chris Froome and former world champion Mark Cavendish, said they felt obliged to show fans that they are committed to a clean sport. "We want a team in which riders are free of the risks of doping and in which fans -- new and old -- can believe without any doubt or hesitation. There is no place in Team Sky for those with an involvement in doping, whether past or present. This applies to management, support staff and riders," added the statement. "Like others, we have been shocked by recent revelations of systemic doping in cycling's past. So we have taken steps to reaffirm our commitment to being a clean team."
